Hydraulic Mono Strand Stressing Jack

Core Executing Component For Anchor Cable Tensioning Systems

The Hydraulic Mono Strand Stressing Jack is the core executing component of underground anchor cable tensioning equipment, serving anchor cable installation and pre-stressing tensioning operations in coal and metal mines. This product applies the standard design pre-tension force to anchor cables, effectively reinforcing surrounding rock and establishing a solid support safety barrier. Compatible with pneumatic, electric, and manual hydraulic pump stations, the unit features a compact structure and easy operation, making it essential equipment for mine roadway support projects. Products have been deployed in bulk to leading coal enterprises including China Energy Investment Group, China Coal Group, and Shandong Energy Group, serving over 60 mining units with consistently positive field feedback.

Our engineering team worked with Chongqing University and China University of Mining and Technology to optimize the jack design. The cylinder body of this hydraulic mono strand stressing jack is crafted using aerospace-grade materials and advanced processing technology, removing all excess weight while maintaining full strength. Through structural optimization and lightweight alloy material upgrades, this product achieves a 20%–30% weight reduction compared to similar industry products. This significantly reduces underground transport burden and operator fatigue, directly delivering on our mission of "Improving the Quality of Labor." The tool anchor's material composition and heat treatment process have also been improved through university laboratory collaboration, significantly reducing replacement frequency and saving both parts costs and downtime.

We offer complete customization for every Hydraulic Mono Strand Stressing Jack. You can choose tension force (200–700 kN), cable diameter, jack stroke (100 mm, 125 mm, 150 mm), and power source type. Our R&D team works with you to confirm every technical detail and match site conditions. Sample development takes 1 to 3 months. All units ship in solid wood cases with quick-release stainless steel buckles. Each part is wrapped in bubble film and fixed securely with cushioning materials inside, ensuring moisture-proof, rain-proof, and shock-proof protection. Cases are clearly marked with product details, model, quantity, and warning signs. We support FOB, EXW, CIF and provide export customs clearance assistance.
